A few weeks ago, I spoke to a Yahoo boy that lives here in Berlin. He was eating at the same Nigerian restaurant I went to eat at, one sunny Sunday. He thought I was a G boy, so was asking me about some stuff I didn't know about, if I knew someone that deal with bank accounts, or if they could use mine to forward hundreds of thousands of euros. I told him no, that I am employed, and jokingly complained about how the tax man is billing me yearly for income tax, that I didn't pay enough the previous year.  Then we got talking and he went on to narrate how he envied ordinary folks that go to work daily, the simple calmness in their soul, and how they could access things that he cannot even access even if he has more money than them. I asked for more explanation, and he continued. He said we do not have the fear of the future, that his affluent reality can come to a stop any day the law ever catches up with him. That when he hears a knock on his door, he fears so deeply to open ev...

WEEK 4 CONCEPT OF CULTURING A pre-requisite to studying microbes is their cultivation under laboratory conditions. Hence, it is important to know the nutrients and physical conditions needed by the organisms. It is easier to grow bacteria, fungi, and algae in appropriate media. The material on or in which microbes grow in the laboratory is called culture medium. Some media are prepared from complex extracts of plant or animal tissues. A culture is the population of organisms cultivated in a medium. If a culture contains only one living species of organism regardless of the number of individuals, it is said to be a pure or axenic culture. A culture which contains two or more species growing together is called a mixed culture. An important medium used for growing microbes is agar. It is a dried polysaccharide extract of red algae which is used as a solidifying agent. It is not broken down by microbes. EVALUATION 1. What is a culture medium

MICRO-ORGANISMS IN ACTION CONTENT • Growth of Microorganisms • Beneficial and Harmful Effects of Microorganisms • Diseases Caused by Microorganisms, Symptoms, Mode of Transmission and Control GROWTH OF MICRO-ORGANISMS Bacteria reproduce by binary fission in which a single cell divides into two. This process is called asexual reproduction. The time interval required for the cell to divide into two is called generation time. This time varies from one organism to another. It strongly depends upon nutrient availability, temperature, gaseous requirement and pH. There are different phases in the growth of bacteria. These include the (i) lag phase (ii) logarithmic or exponential phase (iii) the stationary phase and (iv) decline or death. The growth of micro-organisms can be measured by using any of these methods: (a) Turbidity method. (b) Serial dilution method. (c) Squared transparent paper or cellophane method. BENEFICIAL AND HARMFUL EFFECTS OF MICRO-ORGANISMS BENEFICIAL EFFECTS 1. Bact...

WEEK 3 MICRO-ORGANISMS AROUND US Behavioral Objectives Identify some organisms present in air and water State the characteristics (colour. Pattern of growth, appearance) of colonies of micro-organisms. View some micro-organisms under microscope to identify their pattern DESCRIPTION AND GROUPS OF MICROORGANISMS Micro-organisms otherwise called microbes or germs can be defined as living things which cannot be seen with naked eye but by the use of microscopes. They exist almost everywhere, in water, air, soil, surface of objects, as well as on and within living organisms. They are carried by air currents from the earth’s surface to the upper atmosphere. They occur most abundantly where there is food, moisture and adequate temperature for their growth. It was the invention of microscope that opened the gateway to the world of these minute living organisms. The first person to discover microbes was a Dutch man called Anthony Leeuwenhoek (1632-1723). Using a simple micros...
